100
1012001-02-01      Greg Menke <gregory.menke@gsfc.nasa.gov>
102
103        * mongoosev/vectorisrs/vectorisrs.c,
104        shared/interrupts/vectorexceptions.c: Use rtems/bspIo.h, not just
105        bspIo.h.
106
1072001-02-01      Greg Menke <gregory.menke@gsfc.nasa.gov>
108
109        * Lots of tinkering and tuning as part of improving interrupt latency
110        and improving the per-task interrupt level control and FP mask handling.
111        With these modifications interrupt latency was measured at a worst-case
112        of 100us, average below 60 us on a 12 Mhz R3000 class CPU with 50
113        RTEMS tasks in the application.
114        * mongoosev/README: Updated. 
115        * mongoosev/include/mongoose-v.h: Masks modified.
116        * mongoosev/vectorisrs/vectorisrs.c: Significant overhaul to address
117        software prioritization of interrupts.  If a higher priority interrupt
118        occurs while we are looking for new interrupts, we will reinitiate the
119        scan of all interrupts.
120        * shared/interrupts/vectorexceptions.c: Removed warning and deleted
121        blank lines.
122
1232002-01-03      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
124

126        * r46xx/vectorisrs/vectorisrs.c: Include rtems/bspIo.h instead of bspIo.h.
127        * shared/interrupts/vectorexceptions.c: Include rtems/bspIo.h instead of bspIo.h.
128        * tx39/vectorisrs/vectorisrs.c: Include rtems/bspIo.h instead of bspIo.h.
129
1302001-10-11      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
131
132        * .cvsignore: Add autom4te.cache for autoconf > 2.52.
133        * configure.in: Remove.

135
1362001-09-27      Ralf Corsepius <corsepiu@faw.uni-ulm.de>

140        * mongoosev/duart/Makefile.am: Use 'PREINSTALL_FILES ='.
141        * shared/cache/Makefile.am: Use 'PREINSTALL_FILES ='.
142        * shared/cache/Makefile.am: Use 'CLEANFILES ='.
143
1442000-05-24      Joel Sherrill <joel@OARcorp.com>
145
146        * mongoosev/include/mongoose-v.h, mongoosev/vectorisrs/vectorisrs.c,
147        r46xx/vectorisrs/vectorisrs.c, tx39/vectorisrs/vectorisrs.c,
148        tx39/include/tx3904.h: All exceptions were given low numbers and thus
149        can be now be installed and processed in a uniform manner just like interrupts.
150        Variances between various MIPS ISA levels are not accounted for at this time.
151        * mongoosev/vectorisrs/Makefile.am, mongoosev/vectorisrs/maxvectors.c,
152        r46xx/vectorisrs/Makefile.am, r46xx/vectorisrs/maxvectors.c,
153        tx39/vectorisrs/Makefile.am, tx39/vectorisrs/maxvectors.c,
154        shared/interrupts/maxvectors.c, shared/interrupts/Makefile.am: Split the
155        shared maxvectors.c into a variety of CPU model specific versions to simplify
156        the build process and reduce depdencies.  Deleted shared/interrupts/maxvectors.c
157        and created various CPU model versions.
158
1592001-05-24      Greg Menke <gregory.menke@gsfc.nasa.gov>
160
161        * clock/clock.S: Move placement of nop.
162

166        * mongoosev/duart/mg5uart.c, mongoosev/duart/mg5uart.h,
167        mongoosev/include/mongoose-v.h, mongoosev/vectorisrs/vectorisrs.c,
168        shared/interrupts/maxvectors.c: Now works.  Significant rework
169        of exceptions and interrupt vectoring to clean things up.
170        * shared/interrupts/vectorexceptions.c: Removed.
171
1722001-05-07      Joel Sherrill <joel@OARcorp.com>
173
174        * shared/interrupts/vectorexceptions.c: New file to decode
175        exception code and vector appropriate NON-interrupt exception. 
176        * shared/interrupts/Makefile.am: Modified to reflect above.
177
1782001-04-20      Joel Sherrill <joel@OARcorp.com>

184        MONGOOSEV_PFICR, MONGOOSEV_PFIMR, mongoosev_set_in_pficr,
185        mongoosev_clear_in_pficr, mongoosev_set_in_pfimr,
186        mongoosev_clear_in_pfimr, MONGOOSEV_UART_ALL_IRQ_BITS): New macros.
187
1882001-04-16      Joel Sherrill <joel@OARcorp.com>
189
190        * mongoosev/duart/mg5uart.c, mongoosev/duart/mg5uart.h
191        Modifications made with Gregory Menke <gregory.menke@gsfc.nasa.gov>
192        as he debugged this BSP using a logic analyzer.  In particular,
193        there was a mistake where the index not offset of registers was
194        in the header file and the baud rate calculation was incorrect.
195
1962001-03-13      Joel Sherrill <joel@OARcorp.com>
197
198        * Added mongoose-v, mongoose-v/include, and mongoose-v/vectorisrs
199        directories.
200        * mongoosev/.cvsignore, mongoosev/Makefile.am, mongoosev/README,
201        mongoosev/duart/.cvsignore, mongoosev/duart/Makefile.am,

209        shared/interrupts/maxvectors.c: Added support for mongoosev.
210        * tx39/vectorisrs/vectorisrs.c: Corrected warning.
211
2122001-03-03      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
213
214        * shared/cache/Makefile.am, tx39/include/Makefile.am:
215        Apply include_*HEADERS instead of H_FILES.
216
2172001-01-08      Joel Sherrill <joel@OARcorp.com>
218
219        * Added r46xx directory.
220        * Makefile.am, configure.in: Modified to reflect addition of r46xx.
221        * shared/interrupts/installisrentries.c: Fixed typo.
222        * r46xx/.cvsignore, r46xx/Makefile.am,
223        r46xx/vectorisrs/.cvsignore, r46xx/vectorisrs/Makefile.am,
224        r46xx/vectorisrs/vectorisrs.c: New files.
225
2262000-12-19      Joel Sherrill <joel@OARcorp.com>
227
228        * tx39/vectorisrs/vectorisrs.c: Modified to have default exception
229        vector handler.  This should be in a separate file so the BSP can
230        easily override it.
231
2322000-12-13      Joel Sherrill <joel@OARcorp.com>
233
234        * configure.in: Added new directories.
235        * shared/interrupts/Makefile.am: Added AM_CPPFLAGS to define TX39
236        when compiling for a TX3904.
237        * shared/interrupts/maxvectors.c: Corrected conditional logic.
238        * tx39/Makefile.am: Added vectorisrs.
239        * tx39/vectorisrs/Makefile.am, tx39/vectorisrs/vectorisrs.c,
240        * tx39/vectorisrs/.cvsignore: New files.  This decodes the
241        interrupt pending information on the TX3904 and vectors
242        an interrupt.
243
2442000-12-13      Joel Sherrill <joel@OARcorp.com>
245
246        * shared/.cvsignore, shared/Makefile.am,
247        shared/cache/.cvsignore, shared/cache/Makefile.am,
248        shared/cache/cache.c, shared/cache/cache_.h,
249        shared/interrupts/.cvsignore, shared/interrupts/Makefile.am,
250        shared/interrupts/installisrentries.c,
251        shared/interrupts/isr_entries.S,
252        shared/interrupts/maxvectors.c, tx39/.cvsignore,
253        tx39/Makefile.am, tx39/include/.cvsignore,
254        tx39/include/Makefile.am, tx39/include/tx3904.h: New file.
255        Moved some pieces of interrupt processing from score/cpu to
256        libcpu/mips since many interrupt servicing characteristics are
257        CPU model dependent.  This patch addresses the number of interrupt
258        sources and where the ISR prologues are located.  The only way to
259        currently install the ISR prologues requires that the prologues
260        be installed into RAM.
261
2622000-11-09      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
263
264        * Makefile.am: Use ... instead of RTEMS_TOPdir in ACLOCAL_AMFLAGS.
265
2662000-11-02      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
267
268        * Makefile.am: Switch to ACLOCAL_AMFLAGS = -I $(RTEMS_TOPdir)/aclocal.
269
2702000-10-26      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
271
272        * Makefile.am: ACLOCAL_AMFLAGS= -I $(RTEMS_TOPdir)/macros.
273        Switch to GNU canonicalization.
274
2752000-10-24      Alan Cudmore <alanc@linuxstart.com> and
276        Joel Sherrill <joel@OARcorp.com>
277
278        * This is a major reworking of the mips64orion port to use
279        gcc predefines as much as possible and a big push to multilib
280        the mips port.  The mips64orion port was copied/renamed to mips
281        to be more like other GNU tools.  Alan did most of the technical
282        work of determining how to map old macro names used by the mips64orion
283        port to standard compiler macro definitions.  Joel did the merge
284        with CVS magic to keep individual file history and did the BSP
285        modifications. Details follow:
286        * Makefile.am: Made clock and timer subdirectories conditional.
287        * configure.in: Ditto.
288        * clock/clock.S: Switch from using <idtmon.h> to <asm.h>.
289        * clock/gettime.S: Switch from using <idtmon.h> to <asm.h>.
290
2912000-09-04      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
292
293        * clock/Makefile.am, timer/Makefile.am: Include compile.am
294
2952000-08-10      Joel Sherrill <joel@OARcorp.com>
296
297        * ChangeLog: New file.
